Improvement in cotton-presses



PATENT o'sn'o H. BELDEN, OF NEWBURG, TENNESSEE.

IMPROVEMENT IN COTTON-PRESSES.

Specification forming part of Letters Patent No. 1 74,937, dated March 21, 1876; applicationfiled March 13, 1876.

hereby declare that the following is a full,

clear, and exact description of the same, reference being had to the annexed drawing,

making a part of this specification.

This-invention consists, mainly, in the com- .bination of a pair of levers having two acting-rods, with a single movable beam and clamping-rings, the construction being such that the simultaneous movement of the levers at the ends in either direction will cause the beam to descend uniformly throughout its entirelength.

In the drawing, Figure 1 represents a 1011- gitudinal sectional elevation of my improved press, and Fig. 2 an enlarged view, of one of the levers and its actuating-rods, and also one end of the follower-beam and the clamping-rings attached thereto.

To enable others skilled in-the art to make and use my invention; I will now proceed to describe fully its construction and manner of operation.

A represents the sill or base, constructed of any proper material having suitable strength, which is adapted to support the structure and receive the strain of compression. B represents a beam attached to or resting upon the follower I), having the usual spaces b, as shown. C 0 represent the uprights or standards supporting the upper part of the frame. D rep resents the upper part of the filling-box, which is permanently secured to the standards and provided at its ends with a vertical slot or opening adapted to permit the followerbeam to have its proper movement. D" represents the lower part of the filling-box, the

sides of which are formed of hinged doors, by means of which the bale, when compressed, may be readily removed. f represents a standard strongly secured at its lower end to the base A, in any proper manner, and provided above with suitable bearings for the pivot-pin of the lever. F represents the lever,

which is pivoted near one endto the upper end of the standard f, as shown. E E represent rods of suitable size and material, which are pivoted, at their lower ends, to the lever F upon each side of the fulcrum, as shown. The upper ends of these rods may be caused to extend up through suitable openings in the beam B or to extend by it on either side, as shown. G G represent eyebolts, rings, or equivalent devices, by means of which the clam pingrings are permanently secured to the movable beam at its ends. H H represent these clamping-rings or clutches, each consisting of a suitable ring having a right angle arm,

as shown, which is loosely, but. strongly, at-

tached to the fastening device G of the beam, the part encircling the rod being made heavier than that portion upon the other side of the point of suspension, for the purpose of adapting it to clamp the rod when the latter moves in a downward direction, and to release the same when it moves in an upward direction.

The operation will be readily understood. The press having been properly filled, the levers, at the ends, are simultaneously operated for the purpose of bringing down the follower to compress the bale, the movements of the lever in either direction causi ng the beam to descend, the operation being substantially as follows: When the lever, at either end, is raised, the outer rod is, of course, lifted with it, the heavy ring encircling it permitting this move ment without being affected by it. When, however, the lever descends, the ring, which, in consequence of its overbalanced position, cannot slip upon the rod but is securely clamped thereto, moves with it, and, consequently, pulls the beam down with it. When the outer rod, however, is moving in one direction, the inner rod is also moving in an opposite direction, so that the beam ,is being drawn in a downward direction ateach movement of the lever.

Some of the advantages of this construction are as follows: The position of the lever and the person operating thesame 1s permanently fixed, the necessary vertical movement being made by the beamand clamping-rings.-

The power is equally and uniformly applied at each end of the press, instead of at one point only, so that more persons-can use the levers without inconvenience.

The construction is exceedingly simple, and

not liable to get out of order, and yet very ble beam and clamping-rings,

eflectivc in its action.

Having thus fully described my invention,

what I claim as new, and. desire to secure by Letters Patent, is-

The combination of a pair of levers, each having two acting rods, with a single movasubstantially as described.
